BENTLEY L. RINEHART, OF CAMDEN, NEW JERSEY.

STEAM BOILER OR GENERATOR.

SPECIFICATION forming part of Letters Patent No. 453,391, dated June 2, 1891.

Application filed September 24:, 1890. Serial No. 365,972. (No model.)

To all whom it may concern.-

Be it known that I, BENTLEY L. RINEHART, a citizen of the United States, residing at construction and in the combinations of parts,

as hereinafter more fully described, and particularly illustrated in the accompanying drawings, wherein- Figure 1 is a side elevation, partly in section, of my invention complete, and Fig. 2 is a plan view, partly in section, of the same.

A represents the shell or casing, of a shape best suited to the character of its contents and surmounted by the smoke-stack a.

13 represents a petroleum-vapor burner, located in the base or fire-space of the casing A, for generating the necessary heat, and which may be of any character other than that shown in the drawings, as any special form of fire apparatus is not part of my invention.

G is an upright cylinder or drum supported by legs 0, to prevent their being burned off, and the on the bottom of the casing, said cyldiaphragm 0', extending from the bottom 0 1 partments 0 c 5 and secured in the groove 0 therein, or otherwise conveniently secured, and extending upwardly to about the middle of the cylinder,

thus dividing its lowest portion into two com- The pipe D, which forms one of the supports for the cylinder 0, is substantially L-shaped, having the inclined portion at and the longitudinal or horizontal portion at, the latter terminating in an upright drum or manifold D of the same diameter as the pipe D.

e e are unions or couplings secured in vertically-aligned openings in the manifold for which are hollow and full of water the reception of the ends a of the spiral coils E E E E E E all of which are of the same size and have their respective coils of the same diameter, are arranged nest-like, one above the other in such manner as to bring the smallest coil of one spiral up into the space beneath the coils of another spiral and just below the smallest coil of the latter without touching the same, thus permitting of a multiplicity of spirals being employed without taking up much room.

e are other vertically-aligned unions or couplings secured to the short sections 0 secured in openings in the side of the cylinder 0 for the reception of the inner ends e of the spiral tubes E E, &c.,such openings being in the part of the cylinder which is divided by the partition G into compartment 0. The other compartment 0 which opens into the pipe D, which is secured in a suitable opening in the bottom of the compartment, has therein a vertical pipe F, of somewhat less outer diameterthan the inner diameter of the pipe D, and having its lower end or extension f of the same angle of inclination as the inclined portion of the pipe D and resting and supported within such portion in such manner as to allow of a clear space between the extension f and the portion d, such clear space opening into the horizontal part at of pipe D at one end and at the other end opening into the compartment 0 The upper end of the pipe F is surmounted by a flaring or funnel-shaped mouth f, which at its upper edge is hemispherical in outline or of the same shape as the plan of the compartment 0 such edge almost filling the space be tween the partition C and the walls of the cylinder. As will be observed, the manifold D is provided with the usual gage d supported on the pipe 61 and the cock d 0 is a downwardly-inclined deflector or fender secured inside of and near the top 0 of the cylinder Gin the lugs c or in any other convenient manner, which deflector extends almost entirely across and nearly fills the upper part of the cylinder, projecting entirely across the compartment 0' and almost across the compartment 0 leaving a little space be- &c., will strike against the deflector c and any water therein will thus be thrown into the funnel of the pipe F, and so find its way eventually to the manifold D and again to said tubes, the dry steam in the meantime having escaped around the edge of the fender and into the steam-pipe C The upper part of cylinder has also a tube a, secured in an opening therein and having an outletinto a safety-valve C and another tube g, leading into the usual gage-tube G, the latter being provided with ordinary gage-cocks g and at its lower end communicating through the tube 9 with the lower part of the cylinder 0.

The operation is as follows: The tube 0 being filled with water up to the point a little below the upper edge of the partition 0', and the fire started, as soon as the tubesEE', &c., become sufficiently heated, the water therein being also correspondingly heated, the steam bubbles formed in such water will travel upwardly, owing. to the upward inclination or tendency of said tubes, and avoid thereby the danger of burning the tubes, which would result were such bubbles to remain in any one position for a time, the travel of the steam bubbles continuing in the direction indicated by the arrows in full lines until they pass outof the inner ends of V the tubes and into the water in the compartment 0, and finally through such water until they burst at the surface, whereupon the steam therefrom will rise until it strikes against the fender 0, when it passes around the edge of the fender, as shown by the arrow at the edge of the latter, and finally into the steam-pipe 0 Should any water be carried by the steam as far as the fender, the same will be deflected and thrown into the mouth f of the pipe F, as shown by the dotted arrow just below said fender, while the water that spurts upwardly above the surface of the water in compartment c in the steam-making process will fall into said mouth, as shown by the dotted arrows just below the first-mentioned dotted arrows. The water above mentioned in its passage through the pipe F on its way to the manifold D and the outer ends of the tubes E E, &c., will produce a good and steady pressure in such tubes, and thereby conduce to a good circulation, while the space between the pipe D and said pipe F will, by reason of the water being therein, prevent the heating of the latter pipe to such extent as to cause the formation of steam bubbles therein, which, in passing up through the water in such pipe, would interfere with the downward flow of the same and prevent a free circulation. The diaphragm C being opposite the discharge-openings of the tubes E E, &c., prevents the steam bubbles therefrom from passing over into the position of the compartment 0 where their upward passage would be impeded by the pipe F with its funnel-shaped mouth.
